ZENITH CHRONOMASTER GRAND DATE
The name El Primero alone is enough to evoke its exceptional chronographicperformances, yet this model goes well beyond this capability by offeringvarious useful complications, including a poetic and exclusive display ofthe moon and sun phases. The new El Primero Chronomaster Open Grande DateMoon & Sunphase is available in two versions with a case in rose gold or steel.
An alliance of useful complicationsSince the advent of the first automatic integrated chronograph launched by Zenith in1969, the famous collection of El Primero calibres has constantly evolved, while jealouslysafeguarding its distinctive frequency of 10 vibrations per second (36,000 vibrations perhour), which makes this the only movement capable of measuring and displaying 1/10ths ofa second. Over the more than 40 years since their introduction, the precision and reliabilityof the El Primero chronographs have earned them truly legendary status.
THE OPEN DIAL, A ZENITH SIGNATURETo display these celestial movements at 6 o’clock and the days passing through the largedate aperture at 2 o’clock, Zenith has created a dial with a sunburst motif radiatingfrom the centre (silver-toned or black according to the versions), along with circularsatin-brushed chapter-ring zone and counter zone at 3 o’clock, while the sun and moonaperture at 6 o’clock is sunburst guilloché-worked on its lower section. Representing theemblematic signature of the Manufacture Zenith, the dial opening onto the beating heartof the movement reveals the regulating organ and its high-frequency vibrations, as well asthe meticulous finishing adorning the entirety of this exceptional movement.Available in rose gold or steel versions with a silver-toned or black dial, the El PrimeroChronomaster Open Grande Date Moon & Sunphase features a generous 45 mm-diametercase equipped with round vintage-style pushbuttons and water-resistant to 50 metres.It is fitted with a brown (for the rose gold version) or black (steel version) alligatorleather strap with matching metal buckle.
